This is what I learnt from the teachings :
Faith is what we can not see, according to an American Pastor he believe Faith is not what you cannot see, according to book of hebrew Faith is the substance of things hope for and the evidence of things not see, it is something you cannot see but you believe. Faith comes from what you have seen. The principle of science believe nothing happens without a course i.e there is a proof the bible also believe this too. The God we serve cannot be seen because he is an invisible God. How do you see the evidence that Faith in God is real, we are commanded to look to heaven.The bible believe that the universe have an end, so physical things also have an end and science said matter is anything that have space and can occupy space. Science could not measure what was made by God, so for God he does not have an end. Now we believe there is God.
Faith that is being thought in the bible is the evidence of thing not see, For example we cannot see oxygen , if someone does not have oxygen the person will die. The scientists are wasting their time that Faith in God does not exist. Abraham, Isaac and Jacob they became heroes of Faith. Atheist believe there is no God, so they don't believe in Faith. How can you believe there is no God, how can you say there is no salt and sugar when there is, so why would you say there is no God. Through faith Sarah was able to conceive in the bible, the Faith of Abraham and the wife came because they believe their is a God in heaven.
Faith in God was pass from Abraham to Isaac and Isaac to Jacob and Jacob to others and to the times of christ. It take 100 years before a Bamboo produce a tree. Faith is not something stupid. Faith exist and it is not something stupid, you may not see it but it exist just like love, it is something that exist from generation to generation i.e from Adam and eve to this generation. So who are you to say there is no God. God proves to us through is creation that he exist, so we are advised as a believer of the word of God that our God in heaven exist so we should have Faith in him.
